Analysis of Fat-soluble Components in Raphani Semen by GC-MS

OBJECTIVE To discuss the constituents and reletive contents on fat-soluble components in Raphani Semen. METHODS The oil from Raphani Semen was extracted by ultrasonic technology, then esterified with KOH-CH3OH and analysised by GC-MS. RESULTS There were 27 fat-soluble components identified, inclouding 15 fatty acids components which were accounting for 50.47% of the total components, 12 components had not been reported in documents. CONCLUSION The method is simple, efficient and could be used for the study of the fat-soluble components in Raphani Semen.
